Improvement in elevator-buckets



UNITED STATES PATENT OFFICEo JOHN S. BROOKS, ROCHESTER, NEW YORK.

IMPROVEMENTl IN ELEVATOR-BUCKETS.

Specification forming part of Letters Patent No. 40,671, dated November 24, 1863.

.To all whom it may concern:

Be it known that I, JOHN S. BROOKS, of Rochester, in the county of Monroe and State ot' New York, have Invented a new and Improved Method of Oonstructin g Elevator- Buckets; and I do hereby declare that the following is a full and exact description ofthe same, reference being had to the accompanying` drawings, and to the letters ot' reference marked thereon.

Figure 1 is a perspective view. Fig. 2 is a sectional top View in a line through the rod by which the ends are attached.

Like letters designate similar parts in both the 1i gures.

The nature otiny invention consists mainly in providing elevaorbuckets, which have heretofore been made entirelyot' sheet metal with ends or heads ot' cast metal, iron being preferable, as cheapest, and attaching them to the back and front side by means of a rod running longitudinally through the ceilter, and fastened by a nut and screw. The principal objects and advantages gained by this improvement are superior strength, durability, and cheapness. Theends or heads AA are provided with a i'lan ge or rim around the front and back edges, ot' sufficient depth to receive and hold the sheet-metal part, and also with a series of projecting points, which hold the same from in ward pressure, tht` most ofthe strain on them, however, being outward or against the iiange. The sheet-metal back and front B B can in this way ot' attaching to ends be constructed `ot' a heavier quality of material than could be used if the ends were to be double-seamed to them in the usual manner, and may also be made from the cheapest qualities ot' sheetiron, which would not turn on by the doubleseaming or usual process. The iron known as English7 or common iron of about Nos. 18 to 20 would be about the proper thickness for the back and front, while No. 24 would be the heaviest that could be used in the ordinary manner. The ends can be made at any foundry for the same price per pound that the iron in the sheet would cost if constructed from sheet metal, thereby saving the labor and wastage entirely. About four times that number cati be made with the same amount of work, while l claim that they will outwear double the number when made from the ordinary material. 4

There are a vast number of buckets used in elevators, which are built entirely to aid in the tra'nsshipment of grains at -lake and sea ports, many single elevators using over one thousand buckets, and, from their constant use, last but a short time at best, and any improvement which will cheapen the cost ot' their construction, or increase their durability, would be of great value. In many cases it is believed the cast-iron ends,espeeially if malleableized would bear to be used over and over again with the addition ot' new sheet-metal parts, which would be the soonest worn out, while with the ordinary bucket heretofore used, it' the wearing parts are destroyed, the whole is useless. 'lhe weight will be no objection if the ends are made heavy, as the buckets are attached to an endless belt, which holds an equal number descending and ascending at the same time, while the extra thickness would be much in favor of their durability.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination otcastmetal ends or heads with sheet metal front and back in elevatorbuckets, as and for the purposes shown and described.
